Definitions

  • the invention relates to a device for damping vibrations in a drive train.
  • vibration dampers for damping vibrations in drive trains.
  • Viscous eg, velocity-proportional, hydraulic dampers pump liquids from one chamber to another through a flow resistor.
  • An alternative to hydraulic dampers are friction dampers, as in document FR-A-2 624 225
  • the advantage of a (Coulomb's) friction damper is the construction of materials with linear material properties that do not change over the service life. This makes it very easy to predict the dynamic behavior of the damper with suitable simulation programs.
  • the installed parts can be machined in a conventional manner.
  • the aim of the invention is to eliminate the risk of vibrations in drive trains.
  • the invention is therefore characterized in that a cylindrical shaft, preferably designed as a hollow shaft, is provided around which at least one ring is arranged with friction surfaces.
  • annularly arranged friction elements are also considered to be a ring, wherein here the friction elements extend over a large part of the circumference of the circumference.
  • the ring with friction surfaces acts as a damper element, while the shaft, preferably hollow shaft, is responsible as a spring element for the provision in the starting position.
  • An advantageous development of the invention is characterized in that the friction surfaces are arranged radially on the outside of at least one ring.
  • a favorable embodiment of the invention is characterized in that a hollow cylinder is arranged around the at least one ring, wherein the hollow cylinder can be divided. If a hollow cylinder is arranged around the at least one ring, the mating surface of the friction surface can be advantageously provided on the inner circumference of the hollow cylinder, the hollow cylinder also protecting the (hollow) shaft against contamination.
  • a favorable development of the invention is characterized in that the hollow cylinder or a sub-cylinder thereof has slots which extend axially and are arranged around the circumference of the cylinder, wherein a tangential prestressed tension band or a plurality of tangentially arranged around the circumference biased tie rods may be provided for applying the damper torque.
  • the slots Through the slots, the friction torque can be adjusted well, the damper torque can be applied in a simple manner via a clamping band.
  • Several tangentially arranged tie rods have the advantage that the required force can be well distributed to the individual elements.
  • An alternative embodiment of the invention is characterized in that a plurality of rings are provided, which have friction surfaces on the axial end faces, wherein the rings can form the hollow cylinder.
  • the energy generated during the damping can be divided particularly well.
  • the elements are also particularly easy to assemble or even replace single elements.
  • a favorable development of the invention is characterized in that a plurality of axially biased tie rods are provided for applying the damper torque.
  • the arrangement of the tie rods, the applied force can be well distributed.
  • Fig. 1 shows an isometric view of a first variant of a torsional vibration damper 1 according to the invention.
  • This torsional vibration damper 1 consists of a shaft 2 with flanges 3, which transmits the entire torque from the transmission (not shown) to the bearing shaft (not shown).
  • This shaft 2 with the flanges 3 serves as a torsion spring element of the torsional vibration damper 1.
  • a pipe (hollow cylinder) 4 is fixed, which extends beyond the other flange 3.
  • the tube 4 has slots 5 which extend axially and are arranged around the circumference of the cylinder.
  • To adjust the friction torque is a clamping band 6, which is held together by a screw 7 and biased tangentially.
  • Fig. 2 shows the torsional vibration damper 1 according to the invention in section.
  • the shaft 2 has been shown as a solid shaft, but it can also be advantageously designed as a hollow shaft, thereby weight can be saved. It is also good to recognize the shape of the flanges 3, which are firmly connected to the shaft 2.
  • the flanges 3 are each firmly connected to one half of a coupling.
  • a pipe (hollow cylinder) 4 is fixed, on the other in the circumferential direction (tangential) rings 8 with radially outwardly disposed friction surfaces (12, 12 ') attached, in which case two juxtaposed rings 8 are shown.
  • the rings 8 may also be made by a number of serving as friction annularly arranged slide strips. Depending on the load but only one ring 8 or more rings 8 can be used.
  • the tube 4 encloses here the rings 8 acts on the flange 3 a torsional moment, the torsion spring (shaft 2) is stretched. If the elongation is large enough that the adhesion limit between tube 4 and rings 8 is exceeded, energy is dissipated by the friction.
  • FIG. 3 and FIG. 4 show a second variant of a torsional vibration damper according to the invention, wherein Fig. 1 an isometric view and Fig. 2 to show a section.
  • Fig. 1 an isometric view and Fig. 2 to show a section.
  • flanges 3 with a shaft 2 which can be designed as a hollow shaft, firmly connected.
  • the tube 4 is designed here in two parts and consists of an inner tube 4 'and an outer tube 4 ", which are inserted into one another and have an interference fit, the outer tube 4" has slots 5 here.
  • the friction torque tangential tie rods 9 are arranged around the circumference here.
  • the function of the torsional vibration damper 1, the Fig. 4 be removed.
  • the inner tube 4 ' has a smaller diameter and is provided at its end with rings 8, in which case two rings 8 are shown, but also only one ring 8 or more rings 8 can be used.
  • the tubes 4 'and 4 made as half-shells and firmly connected by means of screws 10.
  • Fig. 5 shows a further variant of the invention.
  • the torsional vibration damper 1 also consists of a shaft 2, which may be designed as a hollow shaft, and is provided at its ends with flanges 3.
  • the shaft 2 acts here again as a torsion spring.
  • the tube 4 is here formed by rings 11, 11 ', 11 ", etc., between which friction surfaces 12, 12', etc. are provided Redundancy. Should a friction couple get stuck, there are others that fulfill the function of the damper.
  • the torsional vibration damper according to the invention can be used wherever there is sufficient space in the axial length of a drive train or is needed.
